2 Claims.

This invention relates to an improved container cover.

One of the objects of the invention is to provide an improved fibrous container provided with a metal ferrule.

Another object of the invention is to provide an improved fibrous container end provided with a metal ferrule for a fibrous container.

Other objects will be apparent from the delo scription and claims which follow.

It has been proposed to produce containers having tubular fibrous body walls and fibrous metal ends joined' by a welded metallic ring loosely associated with a cupped fiber disk. Such l5 container ends cannot be handled readily with I standard can closing machines, In standard can closing machines, the ends for the containers are fed from a stack and handled primarily by the flange. It is a diflicult, tedious procedure to assemble three units, a can body, a metal ring and a fibrous end at one time. The preferable procedure is to handle the preformed end as one unit and the container body as another unit.

The present invention provides a container cover composed of a single unit comprising a fiber disk and a metallic ring which may be conveniently handled in standard can closing machinery.

In the drawing, similar reference characters in 80 the several figures indicate similar parts.

Figure 1 is a fragmentary view, Partly in section, of a fiber disk to which a metal ring has been aflixed.

Figure 2 is a fragmentary view, partly in sec- 85 tion, of a container employing the cover shown in Figure 1.

Figure 3 is a fragmentary perspective view of the container shown in Figure 2. The container cover comprises fibrous disk It 40 provided with peripheral flange l5. Ring l6, of tin plate or other suitable material, is bent and flanged into the cross section shown in Figure 1. I will be noted from this cross section thatimetal ring it has been bent to form a U-shaped flange 45 I! by bends I8 and IS, the cupped portion t5 of disk ll being held firmly in U'-shaped flange II. An outer radial flange 20 is formed by bending corporation of Delaware Application May 29, 1936, Serial No. 82,436

the rim portion of the ring as at 20 and 22. The ring may be welded or not as desired. An unwelded condition is shown as at 26. Container cover' 23 may be afiixed to the body walls'of a container in the manner shown in Figure 2, 5

wherein it will be seen that flange 28 is crimped to the end edge i2 of body wall 63 by a standard seaming machine forming the standard crimp 25.

More specifically, the metal'ring i6 comprises a circular radial flange 2o provided at its inner l0 edge with a substantially U-shaped member W, the cross member of the U-shaped member t'i being extended in substantially the same plane as the radial flange 20.

It will be seen that the present invention 0021- 35 templates a combination flber disk and metal ferrule container cover which may be handled as an integral unit in which one edge of a metal ring is aflixed to the edge of a fiber disk.

I claim:

1. A unit container cover comprising a fibrous disk provided with a peripheral flange and a metal ring for securing the cover within a fibrous container bodywith' the peripheral flange extended outwardly toward the end edge of the con- 25 tainer body comprising a; circular radial flange provided at its inner edge with a U-shaped member crimped over the peripheral flange, the radial flange being adapted for crimping to the outer wall of the fibrous body, the cross member of the U-shaped member being extended in substantially the same plane as the radial flange.

2. In a container including a tubular fibrous body and an end member comprising a fibrous disk provided with a peripheralflange, a metal ring for securing the end within the tubular body I with the peripheral flange extended outwardly toward the end ed e of the tubular body comprising a circular adial flange provided at its inner edge with a shaped member, the cross 40 member of the U-sEaaEd member being extended in substantially the same plane as the radial flange, the U-shapedmember being adaptedto be crimped around the peripheral flange of the end and the radial flange being adapted to be crimped against the outer wall of the tubular fibrous body.
